It was 50 years ago this week when the BBC began broadcasting regular experimental stereo FM broadcasts. While the musical climate and how we get our music has changed considerably since then, there’s no doubt the BBC’s influence on all subsequent media, and recording artists, has been tremendous, especially the far-out sounds that came from its Radiophonic Workshop. To commemorate this anniversary, our very own Tim “Love” Lee (Two For Tennis, Tuesdays at 4pm ET) pays tribute to the BBC’s wild side with Test Signals—a limited-edition EP of electronic strangeness on Lee’s Tummy Touch imprint featuring the help of Tara Busch, Jack Dangers and Si Begg. Stream the EP below, then head here to pick up one of the 150 copies of the 7”, which includes a download featuring bonus remixes from the likes of Sonic Boom, Depth Charge, Kirk De Giorgio and others.
